This would solve your version of the problem. But the original concern
raised was that the whole shebang of glusterfs translators and transports
get installed for someone who wants libvirt/qemu and doesn't care what
glusterfs even is. Your version of the problem is in direct contradiction
with the initially reported problem for which the restructuring was
proposed.
